RAILWAY SAFETY-GATE.

SPECIFICATION forming part of Letters Patent No. 606,259, dated June 28,1898.

Application filed January 3, 1898. Serial No. 665,294. (No model.)

To aZZ whom it may concern:

Be it known that I, HARVEY 0. WILSON, a citizen of the United. States, residing at Birmingham, county of Oakland, State of Michigan, have invented a certain new and useful Improvementin Railway Safety-Gates and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

. which form a part of this specification.

My invention has reference to a novel safety-gate for railway-crossings and the like of superior efficiency, utility, and simplicity; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a view in side elevation showing parts also in section. Fig. 2 is a vertical section through the post, showing features of the interior construction. Fig. 3 is a horizontal section on the line 3 3, Fig. 2. Fig. 4 is a detail view of the shaft 0 with its gear. Fig. 5 is an end view thereof.

One aim of my invention is to provide a safety-gate having rigid connections, not liable to get out of order, and one which may be readily and positively operated.

My invention also aims to secure an increase of power in the operation of the mech anism, and also to enable a gate to be actuated at a considerable distance from the gate-tower, if desired.

I carry out my invention as follows:

In the drawings, A represents any suitable gate-tower, and B any suitable gate-post. Vithin the post is located a shaft (1, provided with a gear 0, which may conveniently be a segmental gear, although I do not limit myself solely thereto, said shaft carrying a gate-arm D, the gate-arm being of any usual construction, and preferably weighted at its lower end, as indicated at D, in a customary manner. Meshing with the gear 0 isarackbar E, made to reciprocate within the post. As shown in the drawings, the rack-bar is en gaged in a guide-bracket F, which may be secured in any proper manner to the post, as by bolts f. This guide-bracket carries also antifriction-rollers f to relieve the friction of the rack-bar in its reciprocation. lo actuate the rack-bar, Ilocate within the tower an actuating-lever G, pawl-and-ratchet mechanism being also provided,as shown, to hold said lever in any givenposition. With the lower end of the lever I engage a rod I-I,'preferably of gas-pipin g, although it might be a solid rod, if desired. Said rod or pipe H is connected at its lower end with a bell-crank I-I, fulcrumed, as at h, to a convenient support H With the opposite end of said bell-crank I engage an additional rod or pipe H which may be located within a boX G underneath the street or pavement, the opposite end of said rod or pipe H being connected with an additional bell-crank J, fulcru med, as shown at j, to a support J. The opposite end of said bell-crank J is connected with the rack-bar, above mentioned, by a connecting rod or bar K. It is evident that by means of said bellcranks and rods or pipes rigid connections are provided between the actuating-lever and the rack-bar, so that the thrust of the actuating lever will positively actuate the rack bar to reciprocate it in either direction, as may be desired. I prefer to provide the rod or pipe H located'underneath the street or crossing, with antifriction guide-rollers, (indicated at L,) journaled upon any suitable support L. Such rollers may be located at suitable intervals and serve not only to guide the rod or pipe H but to prevent its buckling.

The drawings show vertically operating bell-cranks; but I would have it clearly understood that I do not limit myself to any definite location of said bell-cranks, nor do I limit myself to any precise number of bellcranks and their rigid connections. It will readily be understood that by interpositions of other bell-cranks and their rigid connections the mechanism may be adapted for different grades or levels and also for turning corners, if desired. My invention therefore contemplates the employment of any desired number of bell-cranks and rigid connections as circumstances may require, and it will be evident that the rack-bar to throw the gatearm may be just as efficiently and positively actuated by the interposition of more bell- IOC.

cranks, if desired, and their rigid connections as where the grade is level and the connections are straight, as indicated in Fig. 1 of the drawings.

M denotes an ordinary friction -segment upon which the shaft carrying the segmental gear rotates.

It will be evident that an additional gatearm D across the street may be connected with the mechanism hereinbefore described in a very simple manner, as by an additional connecting-rod H and bell-crank N, the bellcrank N connecting an'additional rod N, operating an additional rack-bar E, with the rod H connected with the bell-crank J WVhat I claim as my invention is 1. In a safety-gate, a post, a gate-arm, a shaft j ournaled in said post to carry the gatearm provided with a gear, a reciprocatory rack-bar meshing with said gear, a bell-crank, a rod connecting said bell-crank with said rack-bar, a lever, an additional bell-crank, a rod connecting the last-named bell-crank with said lever, and rigid connections connecting said bell-cranks whereby the rack-bar will be actuated by said lever, for the purpose set forth.

2. In a safety-gate, two posts, a gate-arm carried by each post, a shaft to actuate each of said arms, a gear to actuate each of the gate-arms, a reciprocatory rack-bar to actuate each of said gears, a guide-bracket Within each of said posts in which the corresponding rack-bar reciprocates, antifriction-rollers j ournaled upon said bracket, two bell-cranks, a rod connecting each bell-crank with the corresponding rack-bar, a lever, an additional bell-crank, a rod connecting the last-named bell-crank with said lever, and rigid connections connecting said bell-cranks, substantially as set forth.

In testimony whereof. I sign this specification in the presence of two witnesses.

HARVEY 0. WILSON.
